stack-protector-strong gives performance benefits over
stack-protector-all and is still checking more than -stack-protector,
so seems to be a good middle way and we want to use it when it is
there.
The -shared option for the compiler (not the linker) prevents a
RIM internal version of qcc from forcing -fPIE, and should not harm
in general when set.
In addition, add a method "compilerSupportsFlag" for Windows as is
present in the Unix configure script.

on the way to eliminate scoping based on the spec.
gcc and msvc go as such into CONFIG, the other ones get the vendor
prefixed, as most are mostly unknown and thus likely to clash with
users' flags.

We do not need to include -lang-c++ more than once in QMAKE_LFLAGS*
variables. The fact that this was not appearing more than once was due
to QMAKE_LFLAGS being overwritten (rather than appended to) in
qcc-base-qnx.conf and a weird coincindence in qmake's code to dedupe
libraries passed in to QMAKE_LFLAGS. The deduping was working based
upon options beginning with "-l", including the -lang-c++ option here.

Making -lang-c++ integral part of the $CXX command was wrong, because there are
cases where $CXX must be called without the -lang-c++ file (when building asm
files for instance). This commit moves the -lang-c++ to $CXX_FLAGS where it
belongs.
